Application 4filed January 16, 1902. Serial No. 90.038. (No model.)

To @ZZ whom, t may connerie.-

Be it known that I, GEORGE J. KENNEDY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Pumps; and I do hereby declare the follow ing to be a full, clear, and exact description df the invention, such as Will enable others skilled in the art to Which it appertains to make and use the same.

My invention relates to certain improvements in pumps, more particularly such as are adapted to be actuated by steam or air, usually termed steam-vacuum pumps, for forcing or elevating liquids'tordesired altitudes, which is theA special design of my invention. l

The objects of my invention are, among other thin gs,to provide for the arrangement or location ofthe pump-actuating mechanism atl a readily-accessible or convenient point with relation to the motor or engine, while the pump itself may be located in the bottom of a Well or excavation, for instance, for service.

. Ase

Also,` it provides for greatly simplifying the construction and operation of the parts-as, for example, controlling the exhaust of the steam-pressure from the Waterreceiving chamber-also, the controlling of the vacuumproducing water-spray to saidwater-chamber, together with the delivering of the steam or air pressureinto the last named, all by a common valve mechanism. It also provides for regulating the throw of the steam or air pressure valve according to theamount of watersupply required and for promoting the utility of the pump generally. f

The nature of my invention consists in the combination and arrangement-of parts, including their construction, substantially as hereinafter more fully disclosed, and specificallypointed out in the claims. f

In the accompanying drawings, forming a part of this application and illustrating the preferred embodiment of my invention, Fig- Y ure lis a sectional elevation. Fig. 2 is an enlarged detail section showing more especially the valve mechanism as adapted for a double-acting pump. Fig. 3 is a sectional elevation showing the pump double-acting, the Water-receiving chamber, valve mechanism, vacuum-producing spray-pipe, dac., being duplicated. Fig. 4. is a modification showing the pump double-acting, with the power-- cylinders, having pistons actuating the steam or air pressure supply. valve, receiving their steam or air supply from the duplicate Waterreceiving chambers, rbc. Fig. 5 is also a sectionalvelevation of a further modification, also showing the pump double-acting, with the Water-spraying vacuum-producing pipes supplied from the duplicate Water-receiving chambers, dac. Figs. 6, 7, 8, and 9 are views of a still further modification disclosing a single-valve-casing and a single valve comprising the valve mechanism.

It Will be understood that I do not limit myself to details, as they may be varied as circumstances suggest without departing from the spirit of my invention and the same yet remain intact and be protected. y

In carrying out my invention I employ for receiving the Water or liquid to be raised or lifted a chamber 1,sufticiently elevated in any suitable way in the bottom of a well or excavation--f0r instance, to freely admit the Water or liquid thereinto through a valved opening or port lau in its receiving end or bottom. Said chamber has, as usual, a Water or liquid discharging pipe 1* connected or communicating therewith near its receiving end or bottom and extending upwardly to any required height, according to the altitude of the point of delivery, as will be readily appreciated. Within said discharge ordelivery pipe is arranged or seated near its receiving en d a ball-valve lc, opening or unseating upwardly for the ingress of the liquid and oppositely seating or closing to prevent the return of said liquid after its inl-lux.

4An ai-r or steam supply valve 2 is shown arranged at the upper or top end of the chamber I with its casing or chamber 2X secured to the last named and havinga delivery-port 2 communicating therewith, Said valvecasing has a reduced pipe-like'exteneion 2 at its. upper or one end, adapted to suitably Zconnect or communicate with the steam or Said supply-valve 2 has its rod or stem 2an extended through the upper end of its casing considerably beyond the same, as shown, for a purpose presently seen. A second valve 3 is arranged above and contiguously to the valve 2 and carried by said extension of the stem or rod 2an of the valve 2, with its casing or closure secured to the part 2b for conveniently supporting the same. Connecting or communicating with the chamberof the valve 3 are two pipes 4 4, also communicating or connecting with the water-delivery pipe I and the water-receiving chambers l, respectively. The pipe 4 has a valve 4Arm for regulating the amount of flow of water therethrough, and the pipe 4 extends downwardly into the water-receiving chamber l and is turned or curved upwardly therein gooseneck fashion. Said pipe 4a has its upturned lower end in the water-receiving chamber provided with a foraminous closure, nozzle, or rose 4m to effect the discharge or delivery of the water passing therethrough into said chamber in the form of a spray to produce after the delivery of steam or air pressure into said chamber and the cutting off said pressure, as presently explained, a vacuum to effect, with the aid of atmospheric pressure, the lifting or feeding of the water from below intothewater-receivingchamber. Thevalve 3 is adapted, having ports 4X 4XX, to establish communication therebetween and the pipes 4 4u by the movement of the valve 2, Whose stem or rod carries said valve3, when the lastnamed is closed or the steam or air pressure is cut off from the water-receiving chamber, and thus provide for the delivery of water from the discharge-pipe lb of the chamber l via the pipe 4, the ports of valve 3, and pipe 4 into said Water-receiving chamber. Simultaneously with this action of parts the expanded steam or air pressure will be exhausted from said water-receiving chamber via the exhaust passage or port of the valve 2, then registering with the exhaust-port of its chamber, delivering into the exhaust-outlet 2h. Said pipe4 has a hand-actuated valve 4M to provide for regulating the amount of flow of water therethrough,l and accordingly the size or extent of the water spray issuing from the pipe 4% A power-cylinder 5, also suitably supported or secured for convenience upon the part 2b contiguously to the valve 3, has its piston 5fL secured ,to and carried by the valve-rod extension of the valve 2, said cylinder 5 being provided with a slidevalve 6 of the usual or approved construction, with its housing or containing chamber 0r chest suitably ported and connected up with the steam or air pressure supply for actuating the piston 51. Said slide-valve as commonly arranged has its stem 5b connected to one end of a lever 5, suit-ably supported in position. The other end of said lever is actuated by the rod or stem 2a, carrying the piston 5, in such manner that said slide-valve and piston will be oppositely reciprocated,

and thus provide for admitting steam or air pressure to said piston and exhausting the same alternately, as well understood. Any suitable means may be provided for actuating the lever 5c from the piston-rod, preferably as shown, said lever being forked or bifurcated, as at 7, and having the arms or branches thereof riding upon or receiving the ends of a transverse pin 7, carried by said rod. A second piston or valve 8 is secured to the valve-rod or stem extension 2M, with its chamber or casing 8a for convenience secured or supported upon the part 2b and adapted to contain a quantity of oil or air pressure for regulating the throw or speed of the steam or air pressure supply valve for the water or lifting chamber. Said valve chamber or casing 8 is supplied with a bypass or pipe Sb, connecting with and establishing communication between the opposite ends of said chamber to deliver the oil or air pressure in front of the piston 8 during the performance of its strokes. Said by-pass or pipe 8b is equipped with a hand-actuated valve 8c for va'rying the extent of the flow or passage of the oilor air pressure therethrough from end to end of the valve-chamber E5l as the liquid or fluid is set in motion by the action of the piston 3 of the valve 8C. It will therefore be observed that under some circumstances it is required or desirable that the lifting action of the water receiving or lifting chamber shall be such that the iilling thereof be quite slow-say, restricted to once a minute. In order to compass this, it is only necessary to varythe turning or adjusting of the valve 8C the required degree, which will consequently lessen the amount of flow of the oil or air pressure via said by-pass and Will of course retard the displacement of such liquid or fluid in front of the piston S, accordingly effecting the movement of the valve 5a and the time required to effect the lifting of the water into and the filling of the Waterreceiving chamber.

In the modification disclosed by Fig. 4,showing the pump as double-acting, I employ an additional, preferably valved, pipe 4* for supplying water from the discharge or delivery pipe lb to the chamber of the valve 3, also an additional water-spraying or vacuum-producing pipe 4, dipping into a second waterreceiving chamber 1d and having connection also with the chamber of the valve 3. The valve 2 also has its chamber provided with a second steam or air pressure delivering pipe 2i, connecting with said second water-receiving chamber ld. Communication, it Will be IIO observed, is established between the pipes 4b Y and 4 to produce a vacuum in said second Water-receiving chamber alternately with establishing communication between the pipes 4 and 4a, roducing a vacuum in the first-referred-to water-receiving chamber after the delivering of steam or air pressure into the second water-receiving chamber ld and the cutting od of said pressure from said chamber. Simultaneously with the delivering of the Water spray into said second water-receiving chamber the steam or air pressure supply valve 2 will be exhausting, via its eX- haust-port 2), pipe 2, and pipe 2h, the eX- panded steam, dac., from said second waterreceiving chamber, the inlet-valve of the last named then opening and permitting the lifting of the water intosaid chamber. Upon the closing olf of the water spray said inletvalve of said chamber will automatically close and the inlet-valve of the dischargepipe of said chamber be opened by the pressure of the inflowing water, when upon again admitting steam or air pressure to said chamber the water therein will be forced out through said discharge-pipe, and by the continued alternate repetition of the aforesaid operation of parts both water-receiving chambers will be supplied with water and combined to double the lifting or discharging capacity of the pump.

In the modification as disclosed in Fig. 5, which also shows the pump as double-acting, I also employ two water-receiving chambers 1e 1f, having each a discharge or delivery pipe 2lb 2m, respectively. Said chambers are provided at their lower ends preferably with pendent inlet-pipes 9 9, containing upwardly-opening ball-valves 9b 9c, and said delivery or discharge pipes are equipped with similar valves 9d 9e, also opening upwardly, the action and function of which are the same as the corresponding parts of the forms of the pump heretofore shown and described. At the upper ends preferably of said chambers is arranged a valve 10, contained in a chamber 10, Xed to the said ends of the lirst-referred-tochambers, having a suitable supply-pipe connection 11 with the head or source of steam or air pressure. Said valve 10 has a central exhaust-port 10b and two waterfeeding ports 10c 10c in its face, said port 10b being adapted to alternately establish communication between the atmosphere and the exhaust-steam ports 12 12a of the two waterchambers 1e 1f by the movement of said Valve. Said ports 10c also by the movement of said valve are adapted to alternately effect communication with water-ports 13 13a, having pipe connections 13b 13c with the discharge or delivery pipes 2M 2C. Said ports 10c 10d are further adapted, by the action of the same valve, to alternately establish communication with the ports 13 13, connect-ing with' the water-pipes 13 13d, and the water-spraying pipes 14 14E, 'depending in the two waterreceiving chambers 1e 1f, as shown, to alternately produce the vacuum in said chambers for the lifting of the water thereinto. Steam or air pressure is alternately supplied or delivered into the water-chambers 1- lf from the chamber 10a via, preferably, inverted -T- shaped perforated pipes 15 15, depending a suitable distance into said water-receiving chamber, said supply or delivery of steam or *air pressu re being controlled by the valve 10,

as seen. Said valve has suitably secured to it, about centrally of its upper side, a stem or rod 10e, passi-ng, preferably, through a short upward extension or shoulder lOf of said valve, adapted, as the valve is moved or reciprocated, to play between two cross-pieces or stops 10g, secured or arranged within the chamber 10 to limit the throw or movement of said valve. Said stem or rod 10e extends into two alined power-cylinders 16 l16a, one secured at each end of the casing or chamber 10a, but not communicating `therewith `any further than having openings in their inner ends or heads for the passage therethrough of said rod or stem. This stem or rod has secured to it and carries two pistons 10h 10i, one arranged in each of the cylinders 16 16@ to alternately receive the im pact of steam or air pressure supplied to said cylinders. The cylinders 1G 16a are alternately supplied with steam or air pressure via the water-receiving chambers 1e 1f and pipes 17 17a, effecting communication between said cylinders and said waterreceiving chambers. `Said steam or air pressure supply for said cylinders 16 16a, which initially enters the valve-chamber 10, thence passing into the water-receiving chambers le 1f, thus, after producing a vacuum in the last-named chambers for aiding the lifting of the water thereinto, also drives the pistons which actuate the valve controlling such steam or air pressure supply to said waterreceiving chambers, the pressure-exhausting action in said'chambers, and the supplying of the water spray into said chambers. The speed of the valve mechanism or the throw of the piston in this example of the disclo` 4sure of the principles of my invention is regulated or controlled from the boiler in the engine-room.

In the modilication of my invention as disclosed by Fig. 6, also of the double-acting type, I employ also two water-receiving chambers 1=par 1h, differing somewhat from the last form described. Also applied to the discharge or delivery pipes 32m 3m are two waterspraying pipes 4 4m for producing the vacuum, although not communicating with said discharge-pipes. Said water-spraying pipes have their lower or receiving ends communieating with the opposite water-receiving chambers, thus providing, as the inlet and check valves 3c 3cc 3d 3dd of said chambers and their delivery-pipes are actuated, forl altern-ateylling and emptying the said chambers for the corresponding or alternate spraying of the water from said pipes 1g 1Il in opposite water-receiving chambers, as will .be readily appreciated. At the upper end of the water-receiving chambers 1g lh is arranged a preferably cylindric valve 18,'having a cen- 'tral exhaust-port 18, adapted,` as the valve is reciprocateihto alternately establish com-V munication via the ports 19 19L in the upper ends of the water-receiving chambers 1g 11V with said chambers and the atmosphere.: The chamber 1S", containing the valve 18, has" IOC steam or air pressure ports 18C 18d in communication with the water-receiving chambers 1g 11 via spraying-pipes 19 19a, preferably of inverted -T shape, and depending in said chambers for delivering, as in the last-referred-to modification, the steam or air pressure thereinto. These ports 18c 18d are alternately opened and closed by the valve 18 for the purpose aforesaid, and the valve-chamber 18b is supplied with air-pressure or steam by pipe, as at 18X, leading to the supply of such liquid or fluid, said pipe connecting with one end of said chamber. A suitable pistonvalve 19, whose stem is fixed to the cylindric valve 18, actuates the last named, said valve 19 having its chamber 19X suitably ported and receiving steam or air pressure from the pipe 18 via an intermediate pipe 19, said intermediate pipe 19 also communicating with the ends of the chamber 18b of the Valve 18, as shown. The speed of this valve mechanism or the throw of the piston is also regulated, as in the last-described modification, from the boiler in the engine-room.

In the modification as disclosed by Fig. 7 I arrange upon or in connection with the casing of the water receiving or lifting chamber 1 a'valve mechanism applicable for either a single chamber or duplicate chambers, as in a single-acting or a double-acting pump. Said valve mechanism comprises a continuous casing or closure 2, preferably of a single casting and cylindric in cross-section, and a corresponding cylindric valve 2, also preferably a single casting, having also preferably cylindric extensions 2b, terminating in pistonsor disks 2C, fitting steam or air pressure tight within said casing or closure. Said valve-casing has at suitable or required intervals apart a number or plurality of ports or orifices, the central one, 2d, being for the steam or air pressure supply, the two nearest these, one on each side, 2e, being the steam or air pressure inlet ports, those flanking the last-named, one also on each side, 2f, being the exhaust-ports, and the remaining unreferred-to ones, 2g, being adapted for effecting connection with the condensing or water spraying pipes, as presently seen. Said ports are each preferably annular, being produced en tirely around the valve-body, and

casing and adapted to be alternatelyv opened and closed by the valve 2 to accordingly deliver and cut off the steam or air pressure to and from said pistons and their chambers.

Said valve-casing has also two converging passages 21, communicating with and forming continuatons of the exhaust-ports 2f and having a common outlet. The valve 2 also has at the required intervals apart for registration with the sundry ports'of the valve-casing a corresponding number of ports 2m 2 2o 2P, all except the valve 2m being adapted to be alternately brought into coincidence with the ports of said valve-casing as said valve is reciprocated by the action of the steam or air pressure upon the pistons 2c Within the chambers 2h, more fully seen presently. The central port 2m is of a character, being elongated, to always register or be in communication with the central supply-port 2d of the valvecasing 2 as the valve 2 is shifted or reciprocated to establish communication between said central supply-port and either of the inlet-ports 2e of said valve-casing. There are two of each of the ports 2 2D 2P, and they are adapted to establish communication alternately between the ports 2e, 2f, and 2g of said valve-casing and the ports 1 1b 1, respectively, the ports 1a lb being produced in the walls of the water receiving or lifting chambers 1 1. The ports 1t serve to supply the steam or air pressure to the water receiving or lifting chambers l, the ports 1b exhaust the steam or air pressure from said chambers aftery the cutting 0E said steam or air pressure supply, and the ports 1c open up communication with pipes 5a, delivering water in the form of spray into said chambers simultaneously with the exhausting action of the ports 1b for aiding in producing a vacuum in said chambers. The exhaust-ports 2f are each equipped with a hand actuated valve 2, workingin the Valve-casing 2a, which may be an end-tapered screw-threaded bolt to provide for regulating the exhaust, as will be readily understood. Connection or communication is effected between the ports 1c, opening into the pipes 5E, and the ports 2g ofthe valve-casing 2a, registering with the ports 2p of the valve 2, by means of pipes 5w', suitably secured in place. Said pipes 5M are suitably equipped with hand-actuated valves or cocks 5X to provide for regulating the amount of iow of water therethrough and accordingly the size or extent of the water-spray issuing from their nozzled ends. A valved by-pass channel 2O is produced in the valve-casing 2a, establishing communication between the piston-chambers for supplying oil or air-pressure thereto in front of the pistons 2c to provide for regulating the speed or movement of the valve 2 for the purpose already stated above.
